"Which state that has a good deaf service and WHY!!!" question is pretty general.
I grew up in Texas and enjoyed their VR support for both RIT and Gallaudet. After comparing to friends from different states for VR tution support, Texas is ranked one of the top.
After college, priorities changed like I needed a job. High % of hearing Texans know nothing about ADA and I didnt want to rely on VR to get a job. I got tired of stupid questions regarding deafness and communication. Being a pioneer in educating ADA, it was difficult to get an interpreter for a white collar job interview.
IMO, best places for deafos who want good jobs and have interpreters when needed like interviews, meetings or whatever are Washington, DC and Rochester, NY. More Hearings in both cities are aware of ADA bec of the number of deafos living there.
For instance, I get job leads from companies that employ deafos. With their knowledge in deafness and ADA, they provide terps for job interviews and meetings. My job search is much easier here in DC than Texas and Colorado. DC has long list of terp agencies and my wife works for one of them.
It is not about jobs anymore for me. Like my wife and I are expecting our first baby next month, our local hospital provided terps for our lamaze classes. They even will provide terps for our upcoming labor/delivery and post delivery periods.
Bonus, I used to go to open captioned movies every other weekends in the recent past. I had deaf contractors, a deaf electrician, and a deaf plumber work at my home. I visit one of two DC deaf dentists every 6 months. I also have a deaf CFP.
